Definitions

• Liquid cleaning compositions comprising an aqueous solution containing 20 to 50% of an alkaline potassium phosphate and 15 to 40% by weight of a water-soluble salt of amino alkane sulfonic acids.
• the liquid cleaning compositions of the invention are comprised of an aqueous solution containing 20 to 50% by weight of an alkaline acting potassium phosphate and 15 to 40% by weight of water-soluble salts of aminoalkane sulfonic acids of the formula N-Rr-SOaX wherein R is an aliphatic radical of 12 to 18 carbons which may be interrupted with ether or amino groups, R is an aliphatic radical of 1 to 6 carbon atoms substituted with l to 2 hydroxy which may also contain ether groups, R is selected from the group consisting of alkyl and hydroxy alkyl radicals of 1 to 6 carbon atoms and X is an organic or inorganic water soluble cation, at least 50%, preferably at least 70% of the total cations present being potassium ions.
• the said solutions are clear, aqueous alkaline reacting Washing and cleansing agents with a high content of phosphates and do not require any dissolving intermediates.
• the compositions can contain other known washing agent additives such 3,459,666 Patented Aug. 5, 1969 as silicates, optical brightening agents, disinfectants, whitening agents, agents to control foam and viscosity, etc.
• alkaline acting potassium phosphates which are well known are tripotassium orthophosphate, tetrapotassium diphosphate, pentapotassium triphosphate, etc.
• Suitable amino alkane sulfonates are the sodium salt of N-dodecyl-N-(fi-hydroxyethyl)-3-aminopropane-l-sulfonic acid, the potassium salt of N-(cocoalkyl) N-(B-hydroxyethyl)-3-amino-2-hydroxypropanel-sulfonic acid, wherein the cocoalkyl is a mixture of alkyl radicals of 12 to 18 carbon atoms, the sodium salt of N (4 oxahexadecyl) N-(2,3-dihydroxypropyl)-3- aminopropane-l-sulfonic acid, the potassium salt of N- (4 azahexadecyl) N hydroxymethyl-6-amino-hexanel-sulfonic acid, the sodium salt of N-(mixed alkyl of 16 to 18 carbon atoms) N (/3-hydroxypropyl)-2-aminoethane-l-sulfonic acid
• the salts of the said sulfonic acids are preferably alkali metal and amine salts.
• suitable amine salts are ethanolamine, diethanolamine, triethanolamine, diethylamine, butyl amine and other alkyl and hydroxyalkyl amines wherein the alkyl has 1 to 6 carbon atoms.
• the said aminoalkane sulfonates can be prepared by well known methods.
• One method comprises reacting a primary amine of the formula R NH with a salt of a haloalkane sulfonic acid or with cyclic anhydrides of oxyalkane sulfonic acid to obtain a sulfonic acid of the formula R NHR SO X and treating the latter with agents such as ethyleneoxide, propylene oxide, glycidol, etc. to introduce the R group.
• Another method comprises reacting an amino sulfonic acid of the formula NH R SO H with first an aliphatic halide having 12 to 18 carbon atoms and then with an agent to introduce the R radical such as by hydroxyethylation.
• aqueous concentrates of the invention are exceptionally stable for prolonged storage, entirely clear and remain homogenous even at relatively low temperatures. They are particularly suitable for washing textiles of cellulose and synthetic fibers and for the washing of dishes, tiles, etc. The amount used will depend upon what is being cleaned. As a rule, 0.3 to 1.0 gram of the liquid concentrate is used per liter of dishwashing solution and about 2 to 6 gm. of liquid concentrate per liter for washing synthetic or cotton textiles.
• Example I 25 parts by weight of tripotassium orthophosphate and 15 parts by weight of the sodium salt of N-(4-azahexadecyl) N-(fl-hydroxyethyl)-3-amino-2-hydroxypropane-l-sulfonic acid were added to 60 parts by weight of water to obtain a clear, homogenous liquid with good stability.
• the said liquid was especially suitable for cleaning tiles, floors, etc., and for washing dishes. If a more alkaline solution is desired, alkali metal hydroxides such as potassium hydroxide or sodium hydroxide may be added to the solution to obtain the desired pH.
• Example II One part by weight of a commercial optical brightening agent for synthetic fibers, 20 parts by weight of potassium salt of N-(cocoalkyl)-N-(,3-hydroxyethyl)-3-amino- 2-hydroxypropane-l-sulfonic acid and 40 parts by weight of pentapotassium triphosphate were dissolved in 39 parts by weight of water to obtain a homogeneous liquid, slightly opalescent because of the optical brightener.
